Specification of Letters Patent.

Patented Dec. 24, 1907.

Application filed February 12.1907. Serial No. 357101Z T o all whom it may concern:

Be it known that we, JAMEs P. KARR and JOHN D. RAUGH, citizens ol the United States, and residents oi Logansport, in the county oi' Oass and State oi Indiana, have invented an Improvement in Barges, of which the following is a specification.

Our invention is an improvement in the hulls of barges, boats or 'loats, particularly such as are used to furnish a flat and stable deck or platform for attachment and support of apparatus employed for operating steam shovels or diggers in land or marine excavations. It is a matter of the utmost importance that such barges shall be constructed in the most rigid manner, without unduly increasing the cost. Our improvement attains these objects, and the details of construction, arrangement and combination of parts are as hereinafter described and shown in the accompanying drawings, in which Figure 1 is a plan view of the iframe or body of a barge or boat, the deck or platform being removed. Fig. 2 is a longitudinal vertical section of a portion of the hull. Fig. 3 is a transverse vertical section on the line 3-3 of Figi. Fig. 4 is a face view of a side portion of the hull showing the longi tudinal planking separated in groups or divisions. 5 is a plan view of the parts shown in Fig. 4. Fig. 6 is a side view oi' the barge complete, save that a portion of the deck facing is cut away. Fig. 7 is a perspective view oi one of the divisions or sections composing the bottom of the barge.

The body of the barge is oblong and rectangular. The vertical sides A are formed of a series of groups of side planking 1, Whose meeting ends 1CL are scarfed or cut upon an incline as shownv in Figs. 2, 4, 6, the same being fitted close together and the ends oi the points thus formed being cut vertically so as to form abutting shoulders at 2, see Figs. 2 and 4. Screw bolts 3 pass vertically through the side planking l and top and bottom ribs or beams 6 and 8; and, as shown in Fig. 2, other bolts 3a pass through the scarfed and meeting ends 1 of the side planking, thus connecting them i'irmly but detachably. Additional bolts 4 pass vertically through the side planking, at points intermediate the top beams 6, thus Jfurther securing them together. Parallel to the sides of the barge we arrange interiorly two bulkheads B which are spaced from each other about the same distance that they are spaced from the sides A, see Figs. 1 and 3.

Deck planking 7 is nailed to the cross beams 6. The bottom of the hull is formed in sections C, see Fig. 7, each section comprising side planking 1b having notches or mortises in their under sides and cross beams 8 connecting such planking and projecting through the mortises. These parts are secured together by the bolts 3 as before stated. Planking 9 is nailed t0 the under side of the beams S and the bolts 3 pass through portions of the same as shown in Fig. 2. The sections C are arranged end to end, two beams 8 being thus adjacent and in contact as shown in Fig. 2, and the ends of the side planking 1b abutting as shown in Fig. 2. One of such beams is secured by a short bolt 10 to the side plank which is provided with mortises. Thus, both the sides and bottom of the hull are constructed in separable sections which obviously Oilers a great advantage when it is required to construct the barge at a place distant from that at Which it is to be launched. All the parts composing the hull may be separated from each other and transported in that condition, or if conditions warrant, each hull section may be made up and transported entire. As shown in Fig. 6 the hull is made practically in three longitudinal sections, but of course any other desired number may be employed.

For the purpose oi' applying stress to the hull lengthwise and thus holding the several sections oi the same in rigid alinement, we arrange tie rods 11, see Figs. 1 and 2, directly above the bottom bars or ribs 8 and extending from end to end oi the barge, clevises being provided at the ends for adjustment of tension. 'As indicated in Fig. 1 the clevises are connected with the corner posts 12, which are bolted to both the sides and ends of the barge. We also provide a truss consisting of iron or steel rods 13 which extend Jfrom one end portion of the barge to the other and over beams 14 arranged on the deck, as will be well understood without detailed description.

By the above described construction, arrangement and combination oi parts we form a barge which is comparatively light and inexpensive, yet has great rigidity and durability.

It will be understood that calking is requisite to form tight joints between the side and end planks and the bottom covering as well as between the lower ribs 8 and the side planking in which they are mortised.

at we claim is 1. The improved barge comprising a frame formed in sections consisting of side planks whose ends are scarfed and tted together, longitudinal bulkheads extending trom end to end, transverse deck beams secured to the side planks and intervening bulkheads, and bottom beams arranged transversely and extending through mortises in the lower side planks, vertical bolts passing through the parts named and binding them together and'longitudinal straining rods and truss rods arranged7 substantially as described.

2. An improved barge composed of longitudinal sections which are detachably connected, the meeting ends of the side planks being jointed together, top and bottom beams and ribs arranged transversely and planking applied to form the deck and the bottom of the hull and screw bolts passing vertically through the top 3. The improved barge constructed in longitudinal sections adapted to be separated and each comprising side planks whose ends are scarfed and itted together; bolts passing vertically through the meeting scarfed ends and thus connecting the said sections; top beams arranged transversely; bottom-covering sections comprising planking7 transverse ribs which are fitted inmortises in the lowest side planks7 screw-bolts passing through the side planking and the top and bottom beams or ribs; and straining rods arranged longitudinally of the barge and passing over supports at the center of the same and extending to the bottom and end portions of the barge, as shown and described.
